Ones I have tried recently: Google chrome: Had issues loading images and compatibility with some sites videos wont play in full screen it would show task bar. Firefox: Issues with youtube the browser would keep crashing watching videos with flash. Opera: Some addons are ether not support or out of date compared to firefox or chrome. Then also some issues with sites for some reason loading mobile site when im using opera desktop. Palemoon: Similar issue to opera addon support. Same issue as firefox youtube crashes with flash from some reason but no other site.
Tried that but I get issue with player controls not loading 100% and video not fitting the player. That's using firefox 37 other than that I have no issues with ff just does not want work with youtube. http://i.imgur.com/h4WomWa.png
I suggest you test disabling Flash Protected mode. If doing this works for you, you ll notice the difference immediately. http://www.ghacks.net/2014/12/21/how-to-disable-flash-player-protected-mode-in-firefox/ Bo
